APPARATUS- FOR EXTRACT'ING OIL FROM OIL-"CAKES.

SPECIFICATION forming part of Letters Patent No. 400,254, dated March 26, 1889; Application filed September 5, 1887. Serial No. 248,896. (no model.)

To all whom it may concern:

Be it known that NORRIS LITTELL, a citizen of the United States, residing at Emporia, in the county of Lyon and State of Kansas,

and J OHN L. Moss, formerly of Lowndes county, Mississippi, (THOMLEY A. SoHooLAR, executor of said JOHN L. Moss, deceased,said SCHOOLAR being a citizen of the United States, residing at Avondale, in the county of Jefier- 1o son and State of Alabama,) did invent certain new and useful Improvements in Apparatus for Extracting Oil from Oil-Cakes, of which the following isa specification.

This invention relates to apparatus for extracting oil from oil-cakes without the use of cloth; and it consists in the construction and novel combination of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a View in perspective of one of the improved bands employed in the improved process of extracting oil from oil-cake without the use of cloth. Fig. 2 is a bottom plan view of the band on a 2 5 slightly-reduced scale. Fig. 3 is a horizontal section showing the lock open. Fig. 4 is a plan view of one of the improved polished metal drainage-plates used at the bottom or at any intermediate portion of the band below 0 the top. Fig. 5 is a View in perspective from the under side of the platen used with the band. Fig. 6 is a longitudinal sectional view of Fig. 5, showing the draw-bars connected with the raisingdevers. Fig. 7 is a plan view 3 5 showing the drainage-slots in the top of. the

platen, and Fig. 8 is a plan view of the top drainage-plate.

Referring by letter to the accompanying drawings, A designates one of the improved o bands, which is made of polished steel or other suitable metal, and is substantially rectangular in form. The band is provided with a loose front end, A, and at one side is pro vided withthe slot O to receive the T-head S of the locking-bar D. The said locking bar or rod D is journaled at one end in an opening in that side of the band opposite the slot 0, and its other end is fitted in the slot O and provided with the T-head S. A bracket or lug, A projects from the loose front end, A

of the band and serves as an additional sup port for the locking-rod D. A handle, T, is provided 011 the rod D for rotating the same; The bracket A is not secured to the end A but rests against the same and projects there- 5 5' from, as shown most clearly in Fig. 3. When it is desired to move the end A the rod D is rotated by means of the handle T, so as .to bring the head S into alignment with the slot O. The rod is then moved in the direction of 6c its length, as will be readily understood, todraw the head S through the slot O and up to or nearly to the opposite side of the band, and as the bracket is not secured to the end A it also will be carried against the side of the band, so that the said front end, A can then be removed.

The band A is provided at the bottom with an internal flange, H, upon which the first plate is laid before the meal or formed oilcake is laid in the band. This first plate, which is laid on the flange H of the band, may be in the form of a drainage-plate-such as is shown in Fig. 4. This drainage-plate is made of thin polished steel bars R or other suitable metal riveted to side strips or plates, 0. Small spaces P are left between the steel bars to facilitate drainage, allowing the oil to escape as it is pressed from the meal or formed oil-cake.

S designates the platen, which is provided with flanges S along its sides, and with small grooves S in its upper face, also for drainage of oil. In the under side are recesses S in which the draw-bars T are located, which are employed to lift the band A clear of the platen when withdrawing the band from the oil-press. These draw-bars T are duplicated in the platen,,the duplicate bars being connected together for simultaneous operation 0 by means of the cross-bar U. Levers T are pivoted within recesses S of the platen, and have their inner ends connected to the inner ends of the draw-bars T, the said levers being preferably made triangular in shape. At the rear closed end of the band slots 0 are provided for the escape of the oil from the upper plate.

In Fig. Sis shown the construction of drainage-plate employed at the top of the band.

This top drainage-plate is similar to the one shown in Fig. 4, with the exception that the slots run lengthwise. This plate is provided around the several edges with wide bars Q, which correspond to the flange H of the band. By these improvements a double drainage of the oil as it is pressed from the oil-cake is secured. It is allowed free exit from all points of egress and the mat cannot turn when being inserted. There is less complication in the construction, greater ease and dispatch in working, and a larger production of oil is insured.

In operation the band is filled in the usual manner, a drainage-plate-such as is shown in Fig. 4=being first placed on the flanges 11 of the band. Another drainage -plate (see Fig. 8) is placed on top of the meal in the band, and the latter is then fitted in the boX of the oil-press. The follower of the press as it descends drives the top drainage-plate down into the band, pressing the meal in the usual manner and causing the oil to escape at the rear end of the baud through the slots 0. By providing the drainage-plates at the top and bottom and arranging them in the manner described a double drainage is insured. The platen is first placed on the follower in the press with the drainage-grooves up, the side flanges serving to hold it in position. A drainage-plate is then dropped into the band and the band is filled with meal or formed oil-cakes. WVe sometimes use formed oil-cakes with a plate between them, in which instance we lay the drainage-plate on top and press it down with the hand until it is in place in the band, then turn the whole over and place the band and contents in the oilpress immediately over the platen of the press. hen all of the boxes in the oil-press have been filled in the same manner, the follower is ready to express the oil and the oil passes off in the usual Way to the oil-tank. To empty a band, withdraw it from the oilpress, release the lock, and the plates with the cake will drop out, and the band may be again filled.

Having thus described the invention,what is claimed is 1. The combination of the platen, the levers T pivoted within the platen, and the drawbars arranged within the platen and projecting therefrom and having their inner ends pivoted to the upper ends of said levers T, as set forth.

2. The combination of the platen having the recesses S and S, the draw-bars arranged in the recesses S and connected together, and the levers T pivoted in the recesses S" and connected to the draw-bars, as set forth.

In testimony that we claim the foregoing as our own we have hereto afiixed our signatures in presence of two witnesses.
